The Peggy Hettrick Case - Part 1

Part one of the investigation into the murder of 37-year-old Peggy Hettrick. In February 1987, her mutilated, half-naked body was discovered in a field near the Colorado home of Tim Masters, a 15-year-old boy. He told police he had seen the body on his way to school but, thinking it was a mannequin, did not report it. Masters then became a suspect when police searched his home and found a collection of knives and his graphic drawings of murder and mutilation. But police couldn't find any evidence linking him to the crime and he was not arrested. The case went cold, but ten years later, police would re-open their investigation into Masters. “48 Hours" correspondent Susan Spencer reports.
